Benzoic acid /bɛnˈzoʊ.ɪk/ is a white (or colorless) solid organic compound with the formula C6H5COOH, whose structure consists of a benzene ring (C6H6) with a carboxyl (−C(=O)OH) substituent. The benzoyl group is often abbreviated "Bz" (not to be confused with "Bn" which is used for benzyl), thus benzoic acid is also denoted as BzOH, since the benzoyl group has the formula –C6H5CO. It is the simplest aromatic carboxylic acid. The name is derived from gum ben… WebJul 9, 2024 · 4.63 = 4.2 + log₁₀ [A⁻] / [0.125mol] 0.43 = log₁₀ [A⁻] / [0.125mol] 2.6915 = [A⁻] / [0.125mol] 0.336 moles = [A⁻] That means the student needs 0.336 moles of KC₆H₅CO₂ to obtain the buffer with pH = 4.63.
